PC based Flight Simulators (PC-FS) have been appeared as alternative training devices for pilot training to Enhanced Flight Simulators due to their low cost and absolute availability. Visuals presented in PC-FS are adequate for aircraft pilot training; this is not true for helicopter pilot training due to too low altitudes and speeds. Especially for hovering, increased visual quality is required because of extremely low altitude (3-15 feet) and small movements. In this project, two experiments were conducted by using simple PC-FS as a test platform and professional helicopter pilots as subjects in order to evaluate the effect of hyper texturing on hovering performance. Results have revealed that the level of texture resolution has no direct effect on hovering performance. Optimum texture resolution is dependent upon noticability, recognizability and size of the 2D objects presented by textured image.
